## AI overview

This article argues that database-per-tenant architecture becomes practical at scale when each tenant database is a SQLite file rather than a continuously running PostgreSQL or MySQL server process. It contrasts the cost, connection-pooling, and backup challenges of server-based databases with SQLite's low-cost, file-based model, using Turso as the relevant platform context.

## Source excerpt

The warnings against giving every tenant their own database assume a database is a server process. When a database is a file, the tradeoffs look completely different.
